My grandpa told me when he was a kid, he would take some mud and put it into a napkin or papertowel. Pack it tight and put it in the gun. He said it works just as well as a potato, but its less expensive.

i prefer batteries or spuds, but im tempted about paintballs, is it safe to load a soud then just pile a bunch of painballs in after then shoot the spud wiht the paintballs? or is there some other way to do it?

i dont think he's talking about shoot ppl, i think he's just talking about the well being of himself. i dont see a problem with shoving down a spud and pourin paintballs on it except maybe the paint balls might bust in the barrel, i doubt it though. i think that whould be a cool thing to see. try it. one thing though with my past experiance is that a ball spins in the chamber because it isnt rifles and that causes inaccuracyk but this is not to bad with on eball, but if i fire 2 or 3 at once they start all spinnin differently and start movin each other and then they just fire out the barrel like crazy, so dont expect good accuarcy from the paintballs
